Needlessly gathering facts - Performance issue

[pemsith]

SUMMARY

Since by default Ansible plays gather facts from all hosts, if you are not using any facts in tasks gather_facts should be set to false. There are multiple scripts where ansible facts are gathered but not used, which will be a performance issue.

We have a tool that detects anti-patterns in Ansible, and I'm trying that out with selected OSS repos to see how accurate it is with real datasets.

One of the anti-patterns it detects is 'needless gathering of facts' (gathering Ansible facts even though it's not used). Your feedback is valuable for us to identify issues in our own tool so that we can further improve and provide the tool back to the community for use.
